Summary The voltage across resistors in a series circuit is proportional to their resistances. This rule works because the current in each resistor of a series circuit is the same. Sometimes solder splashes or contamination on the surface of a circuit board affords an alternate path for current to flow. Generally a troubleshooter does not pull out a calculator every time they make a measurement and calculate the current in each resistor using ohms law. They are usually capable checking that the voltage drop across resistors in series is proportional to the resistors indicated value. Intuitive thinking is hard to teach but one aspect can be described. Assume you have a 6K ohm resistor in series with a 1.5k ohm resistor. You can visualize this circuit as being equivalent to 1.5k resistor in series with four 1.5k resistors. Obviously 20% of the voltage will be dropped across 1.5k resistor. Visit our Free online Electronic School The perfect electronics school designed for those who are not going to take for credit electronics courses. This course does not cover all electronics circuits. I will teach you to understand a variety of analog circuits from simple resistor networks up to integrated circuits such as operational amplifiers. I test your ability to troubleshoot all levels of circuits with animated and simulated circuits than contain faults for you to troubleshoot. I aim at developing your troubleshooting skills and hope to provide you with ability to quickly learn about other circuits that you come across. Of course simulated circuits can't harm or electrocute you. You should should get other books, apprenticeships, or go to a real electronics schools to learn about safety and develop soldering skills. That said, I would like to point out that in this computer age, much of system troubleshooting is performed by viewing computer screens displaying diagnostic data.
